java调用deepseek API

### 如何在Java中调用DeepSeek API 为了实现Java应用程序与DeepSeek API之间的交互，通常会采用RESTful Web服务的方式。假设DeepSeek提供了基于HTTP协议的API接口，则可以通过发送HTTP请求来访问这些资源。 #### 使用`HttpURLConnection` 对于简单的GET或POST请求，可以利用JDK自带的`java.net.HttpURLConnection`类来进行操作： ```java import java.io.OutputStream; import java.net.HttpURLConnection; import java.net.URL; public class DeepSeekAPICaller { private static final String DEEPSEEK_API_URL = "https://api.deepseek.com/v1/resource"; public void makeGetRequest() throws Exception { URL url = new URL(DEEPSEEK_API_URL); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setRequestMethod("GET"); int responseCode = conn.getResponseCode(); System.out.println("Response Code : " + responseCode); // Process the response here... conn.disconnect(); } public void makePostRequest(String jsonPayload) throws Exception { URL url = new URL(DEEPSEEK_API_URL); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setDoOutput(true); conn.setRequestMethod("POST"); conn.setRequestProperty("Content-Type", "application/json"); try(OutputStream os = conn.getOutputStream()) { byte[] input = jsonPayload.getBytes("utf-8"); os.write(input, 0, input.length); } int responseCode = conn.getResponseCode(); System.out.println("Response Code : " + responseCode); // Process the response here... conn.disconnect(); } } ``` 上述代码展示了如何通过`HttpURLConnection`发起GET和POST类型的HTTP请求到指定URL，并处理返回的状态码[^3]。 #### 利用第三方库简化开发过程 除了原生方法外，还可以借助Apache HttpClient或者OkHttp这样的开源框架进一步优化网络通信逻辑。这类工具包往往提供更简洁易懂的API设计以及更好的性能表现。 例如使用OkHttp执行相同的操作将会更加直观： ```java import okhttp3.OkHttpClient; import okhttp3.Request; import okhttp3.Response; import okhttp3.MediaType; import okhttp3.RequestBody; public class OkhttpDeepSeekCaller { private OkHttpClient client = new OkHttpClient(); public void performGetCall() throws Exception { Request request = new Request.Builder() .url("https://api.deepseek.com/v1/resource") .build(); try(Response response = client.newCall(request).execute()){ if (!response.isSuccessful()) throw new RuntimeException("Unexpected code " + response); // Handle successful response body as needed. } } public void performPostCall(String jsonDataString){ MediaType JSON = MediaType.parse("application/json; charset=utf-8"); RequestBody body = RequestBody.create(JSON, jsonDataString); Request request = new Request.Builder() .url("https://api.deepseek.com/v1/resource") .post(body) .build(); try(Response response = client.newCall(request).execute()){ if(!response.isSuccessful()) throw new RuntimeException("Unexpected code " + response); // Handle successful response body as needed. } } } ``` 这段程序片段说明了怎样运用OkHttp库完成向DeepSeek服务器提交数据的任务，同时也包含了错误检测机制以确保异常情况能够被妥善捕获并报告给开发者[^4].
